Check the ranger
admin logs at /var/log/ranger/admin/xa_portal.log. If the error is
‘Request failed. loginId=<beacon user>, logMessage=User is
not allowed to access the API’, make sure the Beacon user is
setup as Ranger admin or even DLM engine restart will setup the required
users and their permissions.

org.apache.hadoop.hive.ql.security.authorization.plugin.HiveAccessControlException:Permission
denied: user [beacon] does not have [REPLADMIN] privilege on
[`<dbname>`]

Beacon user should have repladmin privileges in Hive, please set up these
Hive authorisation rules in Ranger.
